Although the effect of irritants on the development of asthma in older patients is less well characterized than in younger patients cefuroxime 250mg low cost medicine misuse definition, exposure to dust parti- cles buy cefuroxime 250 mg lowest price medication 3 checks, art supplies, and cleaning products has been reported to induce asthma in older patients . Diesel exhaust is another potential environmental issue and it increases pulmonary neutrophilia in aged compared to younger mice with a pro- longed pulmonary inammation . However, the effect of infection in older patients with asthma on these stages is less dened. Observational studies have reported that nearly 50 % of subjects with asthma onset after the age of 60 years reported a prior respiratory infection . Detection of respiratory infections is more dif- cult in older patients as viral culture and rapid antigen testing, which are used frequently in the pediatric population are less sensitive in the older population. Although viral infections have been traditionally investigated as an asthma trigger, the role of Chlamydia pneumonaie and other atypical infec- tions has recently come into focus, in particular with adult-onset asthma . Vaccination is an appropriate measure to attempt to alter the immune response and decrease the risk and progression of infectious diseases in older patients. Although vaccination of older patients decreases the progression of many infectious diseases, the immunologic protective response is decreased in the aged [77, 189 ]. In children and young adults, both inuenza and pneumococcal vaccines reduce respi- ratory infections and rates of asthma exacerbation in patients with asthma [190, 191]. The effect of inuenza vaccination or pneumococcal vaccination has not been evaluated in reduction of asthma symptoms in older patients. Recently, high doses of trivalent inactivated inuenza vaccine have been shown to increase the antibody response and increase protection against inuenza in older patients [192 ], which may offer some protection against asthma exacerbations secondary to viral infec- tions in older patients. Two clinical phenotypes have been reported based on the onset and duration of the disease [150, 193, 196]. Some studies of elderly asthmatics have shown that as a group, as many as 40 % will have their rst attack after the age of 40 years [150, 152, 197]. The duration of the disease in this group is an important determinant of severity and of development of irreversible airow obstruction . Dyspnea is a common symptom of many other chronic disorders in older patients such as cardiac or other lung diseases, therefore asthma as an etiology of these symptoms may be overlooked. Many elderly patients limit their activity to avoid getting dyspneic, and others assume that their dyspnea is resulting from their aging process and, thus, neglect seeking medical attention early in their disease process. However, aging per se does not cause dyspnea, and an etiology needs to be always pursued in assessing an elderly patient who complains of breathlessness. Cough is a prominent symptom of asthma and may occasionally be the only pre- senting symptom . Wheezing, on the other hand, may not be as prominent, and its presence is not very specic and does not correlate with severity of obstruction. However symptoms of asthma in the elderly are non-specic and may be caused by a variety of other conditions. History of atopy is a strong predictor of asthma in this age group, and allergic rhinitis, sinusitis, and nasal polyps are not uncommon. Physical examination should focus on ruling other causes for respiratory symptoms such as cardiovascular disease and identifying comorbid conditions such as rhinitis/sinusitis and atopic dermatitis. Lung function testing is especially important in this age group since there is an age-related reduc- tion in the perception of dyspnea seen in the elderly . Unfortunately, objective measures of lung function such as spirometry and peak ow measurements are gen- erally underutilized in elderly patients and this also contributes to the delay in diag- nosis [19, 201]. Furthermore, spirometry may be difcult to perform in some situations, because of physical and poor cognitive impairment.
